Troubleshooting VLOOKUP: Fixing Out of Bounds Errors
VLOOKUP is a handy tool in Excel for finding data, but sometimes it throws an "out of bounds" error. This happens when you’re trying to look up a value that’s not within the range you’ve defined. To fix this, you need to ensure that the column you’re trying to access is within the table array you’ve selected. By adjusting your table array or correcting the column index, you can solve this error and make VLOOKUP work smoothly.
Troubleshooting VLOOKUP: Fixing Out of Bounds Errors
Let’s dive into how to fix these pesky "out of bounds" errors in VLOOKUP. By following these steps, you’ll ensure that your lookup operations run without a hitch.
Step 1: Identify the Error
First, verify that the error is indeed an "out of bounds" issue.
Check if Excel is showing an error message that says the column you’re trying to access doesn’t exist within your selected range. This will confirm the problem.
Step 2: Check Table Array
Next, inspect the table array in your VLOOKUP formula.
Make sure that the range you’ve selected covers all necessary columns. The table array should include at least as many columns as the column index number you’re referencing.
Step 3: Verify Column Index
Ensure that your column index number is correct.
The column index number in your VLOOKUP formula should not exceed the number of columns in your table array. Adjust this number if necessary.
Step 4: Adjust the Range
Modify the table array to expand the range if required.
If the correct data isn’t within the current range, widen it to include all the necessary columns. Double-check to ensure you’ve included everything you need.
Step 5: Test the Formula
Finally, run the VLOOKUP again to see if the error is resolved.
Check if the lookup now returns the correct value. If not, revisit the steps above to ensure everything is properly set up.
After completing these steps, your VLOOKUP should function without the "out of bounds" error. You’ll have access to the data you need, and your formulas will operate smoothly.
Tips for Troubleshooting VLOOKUP: Fixing Out of Bounds Errors
- Always double-check your table array to ensure it includes all necessary columns.
- Use the column index number carefully, matching it to your table array.
- Consider using absolute references (e.g., $A$1:$C$10) to prevent accidental changes to your range.
- Test your VLOOKUP formulas with different data to ensure robustness.
- Use named ranges for easier management and less error-prone formulas.
Frequently Asked Questions
What causes an "out of bounds" error in VLOOKUP?
This error usually occurs when the column index number exceeds the number of columns in your table array.

Yes, just include the sheet name in your table array reference, like ‘Sheet2’!A1:C10.
What if VLOOKUP returns the wrong data?
Check your column index and table array. Ensure the data is sorted correctly if using approximate match.
How do I know if my column index is correct?
Count the columns in your table array from left to right and ensure the index number doesn’t exceed this count.
